摘　　要：本文实现了一种基于嵌入式Linux的B超图像打印方案,可以在多种常用喷墨打印机上输出256灰度级的超声图像硬拷贝。通过对个人计算机Linux下的打印系统的分析,提出了符合本文需要的剪裁方案,交叉编译后的打印模块仅有600k字节。该打印模块在由嵌入式Linux系统和32位微处理器ARM9200所构成的软硬件平台上运行正常,打印质量和速度都符合小型B超对于图像硬拷贝的要求。打印控制则通过运行于Linux上的用户界面MiniGUI实现。A printing solution on the embedded Linux system was designed and implemented, which could be used to output the hardcopies of 256-grayscale B-mode ultrasound images by various types of inkjet printers. A typical printing system based on the personal computer was analyzed and tailored to fulfill our requirement. The final volume of our printing module had only 600 kilobytes after cross-compiled, which worked well on the operational system of embedded Linux and the hardware platform of 32-bit embedded microprocessor ARM9200. The printing quality and speed met the requirement for the portable B-Mode ultrasound scanners. Printing control was performed with a graphic user caninterface called MiniGUI for embedded Linux.
